YSB Series Megatorque Motors

NSK, already recognized for introducing low-priced direct drive

motors, has launched a new Megatorque Motor Series with enhanced

functions whilst still maintaining a low cost.

The YSB Series Megatorque Motor is suitable for a variety of industrial

applications, including indexers in production equipment,

semiconductor manufacturing and transportation equipment. Most

notably, the Megatorque Motor has an absolute position sensor to

omit Homing as standard equipment. In addition, the Megatorque

Motor makes the functional improvement of random matching of

motors and driver units to cut down the number of assembling steps

and production management costs, as well as many other features

that combine to reduce costs while increasing production efficiency.

NSK proudly introduces the YSB Series Megatorque Motors, providing

customers with sophisticated functions at low prices.

Features of YSB Series Megatorque Motors YSB Series Megatorque Motors

Point 1: Direct DriveThe Megatorque Motor is capable to drive the loaddirectly without using a mechanical speed reducer,and accordingly, it realizes highly accurate positioningwithout backlash and lost motion. A MegatorqueMotor is a servomotor that equips a position detectorto form full closed loop control.

Point 2: High Accuracy The YSB Series Megatorque Motor incorporates ahigh-resolution position detector (resolver) thatfeatures 819 200 pulses/revolution. This contributes toan exceptionally precise repeatability of ±1.6 arcseconds.

Point 3: High ReliabilityThe Megatorque Motor is a brushless motor and doesnot use permanent magnets in its simple construction.It is equipped with a highly rigid and accurate rollerbearing (crossed roller bearing), which is packed withlubrication grease, thus offering highly reliable andlong-term maintenance-free operation.

Point 4: Highly Functional Driver UnitThe YSB Series Megatorque Motor constitutes asystem in combination with an ESB Driver Unit for adigital servo control incorporating a 32-bitmicroprocessor.The ESB Driver Unit has a number of command inputsnecessary for motion control, thus permitting itsconnection with sequencers, a variety of positioningcontrollers and personal computers, etc. In addition,acceleration profiling and networking functionsthrough various field buses are available.

Point 5: Include Absolute Position Detectoras Standard Equipment

The YSB Series Megatorque Motor has an absoluteposition detector as standard equipment. Thiscontributes to eliminate the troublesome Homing andthus improves productivity. Additionally, the motorsand the driver units can be randomly matched as apair. Cable can be freely selected up to lengths of 30m.

Point 6: Conformity to the InternationalSafety Regulations

The Megatorque Motor systems conform to the ECDirectives (CE Marking) and Underwriters’ Laboratory(UL) regulations.

Notes:(1) When using the highly accurate absolute positioning type, motors and driver units are not interchangeable.(2) A motor equipped with an incremental position sensor is also available. Please consult with NSK.(3) Consult with NSK if the motor rotates in one direction continuously at a high speed exceeding 2 (s-1), or oscillates in a very minute angle. Maintain the flatness

of motor mounting surface 0.02 mm or less, and mount the jigs so that its center alignment is not off the rotational axis of the motor. Otherwise it will adverselyaffect the life of the motor.

(4) IP30 is defined as below in a regulation of IEC 529 (International Electronics Commission). First digit following IP indicates the protection grade against solids. The number 3 indicates protection against penetration of a solid of 2.5 mm or larger into anenclosure. The second digit indicates the protection grade. The number 0 means there is no protection against water.

(1) Set with internal parameters of the ESB Driver Unit. (2) Braking the motor with the integrator ON causes the motor to continue to supply the maximum current causing the motor to overheat. The integrator should be

OFF while the brake is functioning and turned it ON only before releasing the brake.

The BRK output of CN2 can be used for brake control.

When connecting inductive loads such as a relay, as shown above, to the driver unit output, the rated voltage ofloads should be 24V DC and the rated current should be 100 mA or less. Be sure to provide surge protection.

Be sure to use the attached protective element (marked with in the above wiring example) to protect againstsurge currents.

This is a power-off activated electromagnetic brake that functions with a negative charge.

The 24V DC power supply is not included. The M-FZ063-1 (90V DC) brake power unit for the YSMegatorque Motor cannot be used.

Be sure to keep iron powders or oil away from brake surfaces.

Iron materials near a brake may interrupt operation; therefore allow for at least 15 mm clearancearound the brake during installation.

It is essential to study the allowable load and output torque that requires positioning the motor at a desired time.Refer to the motor specifications for the allowable axial and moment loads. Use the following formulas to obtainan actual load to the motor.

7.2 How to Use Charts for Minimum Positioning Time

7.1 Estimation of Actual Load

Following the check of allowable loads, study the minimum time required to position the motor. The charts provided below are for checking the minimum positioning time of the YSB Megatorque Motors. Refer to the chartsin the following cases. The user wishes to know which motor size should be selected for positioning within a required time, when the

indexing angle and the load inertia are predetermined. The user wishes to know the required time for positioning, when an indexing angle, the load inertia and the motor

size are predetermined.

These charts can be used only when the following conditions are satisfied;1) The load is directly coupled to the rotor, neither using a mechanical speed reducer such as a belt or gears nor coupling, and

is sufficiently rigid (natural frequency is 50 Hz or over).2) No load torque is applied on a motor.

In addition, further examination is recommended when a motor is to be used in any of the following conditions.a. Load inertia exceeds the allowable value so that it may not appear on the charts: Even in this case, driving a motor is not

always impossible, but may take a longer time than the theoretical value because considerable limitations will be placed onthe acceleration and the rotational speed.

b. When there is no chart applicable to the indexing angle: Separate calculation shall be made. However, the minimum timefor positioning cannot be obtained when the indexing angle is too small.

c. The settling time of 0.2 seconds is added initially. You may change the settling time to be shorter if you can relax therepeatability.

Notes:(1) For pulse train (line receiver format) position command, the last 2 digits of the driver unit reference number

change to 01 from 00.

Example: Internal program 16 channels (16 acceleration profiling patterns), pulse train (line receiver format) M-ESB-YSB2020AB301

(2) The driver unit compatible to field bass does not provide the pulse train input function. Therefore the last digits ofits reference number are 00 only.

YSB Series Megatorque Motors9. International Safety Regulations

9.1 CE Marking Low Voltage Directive

NSK has worked with an EU Notified Body and an EU

Competent Body to ensure that the YSB Series

Megatorque Motor Systems conform to the pertinent

regulations of the EC Low Voltage Directive, thus any

system of the users, into which the Megatorque Motor

is incorporated as a “component,” can easily conform

to the EC Directives.

Electromagnetic Compatibility DirectiveWe set conditions on the installation distance and

wirings between a YSB Motor and an ESB Driver Unit

and checked them for compliance with the pertinent

regulations of the MC Directive. Naturally, the way to

incorporate a YSB Motor and an ESB Driver Unit into

your system may differ from our checking conditions.

The users therefore require a final inspection of their

systems which incorporate a Megatorque Motor

System for conformity to EMC Directive (radiated

noise and conducted noise).

9.2 Underwriters’ Laboratory (UL) Motor

Conforms to UL1004 regulation.

(File number: E216970)

Driver UnitConforms to UL508C regulation.

(File number: E216221)

Cable SetWe use the material conforming to the UL regulations.

If you require more detailed information such as installing

conditions, please contact your local NSK

representative.
